Educators seek to develop students' mathematical knowledge retention to increase student efficacy in follow-on classwork, improvement of test scores, attainment of standards, and preparation for careers. Interactive visuals, feedback during problem solving, and incorporation of higher-order thinking skills are known to increase retention, but a…

This paper presents some results of an investigation on the number sense of a group of pre-service secondary teachers from Spain. The objective of this research was to analyze students' use of strategies associated to number sense and compare them with those obtained in a previous study with pre-service primary teachers in Taiwan, (Yang, Reys…

Objective: Limited time and resources necessitate the availability of accurate, inexpensive and rapid diagnostic aids for Autism Spectrum Disorder (ASD). The Autistic Behavioural Indicators Instrument (ABII) was developed for this purpose, but its psychometric properties have not yet been fully established. Method: The clinician-rated ABII, the…

In this clinical study on helping students prepare for an exam, we compared three different treatments. All students were asked to take a practice exam. One group was then given worked-out solutions for that exam, another group was given the solutions and targeted exercises to do as homework based on the result of their practice exam, and the…

The assessment of student learning outcomes in the tertiary school sector has seen an increase in global popularity in recent years. Measurement instruments that target higher order skills are on the rise, whereas assessments that foster the recall of factual knowledge are declining. The Assessment of Higher Education Learning Outcomes (AHELO)…

Background: High-stakes assessments, such the Graduate Records Examination, have transitioned from paper to computer administration. Low-stakes research-based assessments (RBAs), such as the Force Concept Inventory, have only recently begun this transition to computer administration with online services. These online services can simplify…

This paper presents and analyses the results obtained by applying Active Learning techniques in overcrowded Physics lectures at the University of the Republic, Uruguay. The course referred to is Physics 1, the first Physics course that all students of the Faculty of Engineering take in their first semester for all the Engineering-related careers.…

Considerable debate continues regarding the efficacy of the website RateMyProfessors.com (RMP). To date, however, virtually no direct, experimental research has been reported which directly bears on questions relating to sampling adequacy or item adequacy in producing what favorable correlations have been reported. The authors compare the data…

This study examined similarities and differences in measurement properties and score comparability of the "Supports Intensity Scale-Adult Version" (16-64 years) and the "Supports Intensity Scale-Children's Version" (5-16 years). Data were collected from 142 adolescents with intellectual disability with both versions of the…

The dimensional comparison theory (DCT) focuses on the effects of internal, dimensional comparisons (e.g., "How good am I in math compared to English?") on academic self-concepts with widespread consequences for students' self-evaluation, motivation, and behavioral choices. DCT is based on the internal/external frame of reference model…

The question of equivalence between two or more groups is frequently of interest to many applied researchers. Equivalence testing is a statistical method designed to provide evidence that groups are comparable by demonstrating that the mean differences found between groups are small enough that they are considered practically unimportant. Few…

This study examines the impact of inclusion on secondary students by focusing on the performance of students without disabilities in the inclusive environment compared to their performance in a segregated environment. Many studies exist demonstrating the positive impact of the inclusive environment on the performance of students with disabilities.…

Expertise in searching and evaluating scientific literature is a requisite skill of trained scientists and science students, yet information literacy instruction varies greatly among institutions and programs. To ensure that science students acquire information literacy skills, robust methods of assessment are needed. Here, we describe a novel…

Instructional labs are widely seen as a unique, albeit expensive, way to teach scientific content. We measured the effectiveness of introductory lab courses at achieving this educational goal across nine different lab courses at three very different institutions. These institutions and courses encompassed a broad range of student populations and…

This article illustrates how a new framework for conceptualising comparability has the potential to help assessment professionals to understand and to conduct debate on linking theory and practice. The framework was used as a lens through which to study a corpus of research reports, from which a narrative was constructed to characterise the…
